All Five Eyes (1970)

Set in a small English village in 1967, liberated Marion is exploring the new social freedoms enjoyed by women in the late 1960s while conscientious and self-conscious Cecily runs the local girls school and is Willa’s main carer. Their differences reach a boiling point over their relationship with Willa, which leads to each sister making their own decision on what it means to have a life worth living.
